Aoi Tsukiko

Some info: Tsukiko is considered a beauty among the students and appears to be very quiet and soft spoken but is actually quite talkative and smiles more often when she's in her group of friends (Akihiko, Mimi, and Ryu). Not only she's considered a beauty, but an intelligent one as she is placed in higher level classes. Tsuki is like a motherly figure since she cares about her friends and worries about them, treating them like her kids.

• Akihiko and Tsukiko are actually cousins, not siblings.
• She performs as a mermaid at the aquarium from time to time and is popular among the guests there.
• Known to be proper to a certan extent.
